Cats can eat many dog treats safely. But some contain ingredients that are toxic to cats.

I’m a veterinarian and a cat caretaker. I’ve noticed that some cats enjoy eating the occasional dog treat, even the ones that are not safe for them! I’ll give you clear guidance on which dog treats are safe for cats and which ones they need to avoid. 

Read on to learn about the most common three ingredients in dog treats that are toxic to cats.

3 Ingredients to Avoid in Dog Treats for Cats

Cats are not just a smaller version of dogs.

They are unique creatures with their own nutritional requirements and sensitivities. Three common ingredients in dog treats can cause some major health problems for cats.

  • Onion, onion powder, onion extract: These contain a natural compound that causes damage to red blood cells, leading to anemia. (2) While dogs can tolerate small amounts, cats are particularly sensitive to its effects. Symptoms may not appear for up to 7 days after eating onion-containing foods. 
  • Garlic, garlic powder, garlic extract: Garlic is in the same family as onions (allium) but it’s even more toxic to cats. (3) As little as ¼ teaspoon of garlic powder can cause life-threatening anemia in cats. Eating smaller amounts regularly can also cause problems.
  • Propylene Glycol: Often used in semi-moist dog foods and treats as a preservative. In cats, it can cause anemia, depression and a wobbly gait. Even low dietary levels (as little as 6%) can be harmful. (1)

When reading labels, look out for these ingredients and avoid treats containing them to keep your cat safe and healthy.

Safe Dog Treats for Cats

  • Dog Jerky: Choose jerky treats made only from dehydrated meat. Avoid toxic components like garlic, onion, or propylene glycol. Waggin’ Train Chicken Jerky for Dogs are a good example of dog jerky treats that are safe for cats. 
  • Dog Chews: Rawhides and bully sticks are typically safe, but avoid those with harmful additives. Monitor for any digestive issues.
  • Peanut Butter Dog Treats: These can be safe as long as they are free from garlic, onion and propylene glycol.
  • Dog Biscuits: Milk-Bone classic dog biscuits don’t contain any dangerous ingredients for cats. If you use a different brand, always check the label for harmful substances.

Treats should be given in moderation and should not replace a cat’s regular diet.

Pet Treats That Are Safe for Both Dogs and Cats

A great treat option for both dogs and cats is dehydrated turkey breast. This type of treat is well-loved by both species and offers a simple, nutritious snack. 

A brand I’ve had good luck with is Whole Life Pet Just One Turkey, known for its quality and freshness. 

These treats can be easily broken into small pieces, making them perfect for training or as rewards.

Frequently Asked Questions (FAQs)

A: If your cat has eaten more than a bite or so of dog treats with potentially harmful ingredients, you should take them to see a veterinarian. If you notice vomiting, lethargy, or changes in appetite, consult your veterinarian immediately.

A: Generally, it’s not recommended for cats to eat dog bones. The size and hardness of bones meant for dogs could pose a choking hazard or cause dental damage to cats. 

A: Bully sticks are typically safe for use as cat treats if they don’t contain toxic additives. However, due to their size and toughness, they might not be the best choice for cats. Always make sure that any cat treat you offer is appropriate in size and texture to prevent choking, tooth damage or digestive issues.

Conclusion

While many dog treats are safe for cats, you should avoid those with toxic ingredients like onions, garlic, and propylene glycol. 

If you have dogs and cats who insist on sharing treats, focus on those suitable for both cats and dogs, like dehydrated turkey breast. Always check the treat label and consult a vet when in doubt.
